Orzo rice is cooked in salted, boiling water for 10 minutes with occasional stirring to prevent sticking, according to Better Homes and Gardens. When the orzo is done, it is drained in a colander to remove the water.
Orzo rice is actually a variety of pasta that is shaped to look like rice. Like other pastas, it is made from semolina flour. Orzo cooks faster than rice to create a quicker side dish. Nice accompaniments to orzo include olive oil or butter, fresh chopped herbs and Parmesan cheese. Orzo also makes a nice base for gravies and sauces. Cold or leftover orzo works well with raw vegetables and vinaigrette for a hearty salad.
